I have the same problem, but even with a plugged laptop until it refreshes the
few the first time. Annoying thing is, that it shut my laptop down on very
boot when I had automatic shutdown switched on (lol). More strange is, that
the percantage shown IS correct - only the time left isn' t. So I think there
is a bug in the function where the time left is calculated (signum error
perhaps, -1 = 0 ?).
I mailed the author if it would be possible to enter a time and/or a
percantage for warnings in later versions, but he only responded: "No."

Sry. I someone has more luck to get it working, pls mail me. Nevertheless it's
a great tool.

Hi all,

I am running sid, using kde and kdelaptopdaemon (including the KLaptop
applet). When I unplug the laptop (ie it runs from the batteries or is
started unplugged) the KLaptop daemon tells me after about 30 secs:

"Battery power is running out!
0 minutes left."

, although KLaptop actually reports about 3h of remaining battery time (which
is true).
This only happens to 3 (including root) of my 4 users. The forth user account
(my most often used one) does not show this behaviour.
